Although light beams do not interact in vacuum, the propagation in a nonlinear optical medium alters this situation completely. If the nonlinear medium is a plasma, two intenselasers can interact with each other, forming spiraling and braiding patterns when they carry an initial amount of angular momentum [1,2]. According to previous analytical and numerical calculations considering the ...
In this research, we studied the interaction between the ultra-intenselaser and multiple copper layers covered with multiple hydrogen layers. The research conditions are based on the symmetric and asymmetric structure of multilayer copper and hydrogen. It was found that the acceleration obtained from the first copper and hydrogen layer plasma was higher and occurred earlier than the second ...

California, USA — Although light beams do not interact in vacuum, two intenselasers can interact with each other in a nonlinear medium, forming spiral-ing and braiding patterns when they carry angular momentum. Here, we analyse the interaction between N laser filaments ...
Theoretical simulations show that when the ultra-intenselaser was irradiated in multiple copper layers coated with multiple hydrogen layers targets, some plasma phase-space distribution varied ...

TodayShot-to-shot fluctuations of peak power of intense, mid-infrared laser pulses, propagating in a gaseous medium, result in large shifts of the optical phases of the pulses. The authors show that ...
6 days agoa Schematic diagram of the interaction between laser and multilayer targets. The red cone represents the laser pulse. b, c and d correspond to the cases of different laser driving modes.b The case 1 is the overlap of two laser pulses in front of the target, that is, at the focus point.c The case 2 is the irradiation of a single laser pulse.c The case 3 is two laser pulses do not overlap in ...
Jul 19, 2024We have focused on the fact that power-law acceleration is universally observed from the study of laser acceleration and are promoting the possibility of laboratory astrophysics of cosmic ray acceleration using ultra-intenselasers and the physics elucidation of stochastic acceleration. 2,8-12 In this study, we show that power law spectra with its index near 2 are widely obtained in laser ...
Theoretical simulations show that when the ultra-intenselaser was irradiated in multiple copper layers coated with multiple hydrogen layers targets, some plasma phase-space distribution varied clearly in the different thicknesses of the first hydrogen layer or first copper layer, while some plasma were not influenced by the thickness of these two layers. In this research, we studied the ...
